SIDE FRAME.

To all whom it may concern:

Be it known that I, EDWIN E. SLICK, a citizen of the United States, residing in the borough of Westmont, in the county of Cambria and State of Pennsylvania, (whose post-oflice address is Johnstown, Pennsylvania,) have invented certain new and useful Improvements in Side Frames; and I do hereby declare-the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a side frame adapted for use as a part of a railway car truck and especially in connection with the I make my side frame of wrought or. rolled steel which provides a material best adapted to withstand the loads and impacts to which it is subjected in service, and this material, by its method of manufacture, inspection and tests,

can be made solid and integral throughout every portion, and the different parts may be of any quality or strength desired so that each is best adapted to withstand the stresses towhich it will be subjected.

I also prefer to secure the parts together by means of either hot or cold driven rivets of large size, firmly upset and expanded into smooth holes which may be reamed or drilled to cause their surfaces to be of uniform size and smoothness throughout.

My truck is generally composed of three principal members, one of which is the lower arch bar member which is bent into the gen eral form of an extended V with a horizontal lower portion, inclined side portions extending diagonally to the upper parts, and approximately horizontal end portions which are adapted to rest upon and be secured to the journal boxes. Secured to the lower arch bar at the. end portions thereof is the upper arch bar which may be either straight or cambered, and between these two portions I provide a U-shape member, the lower part of which is secured to the lower intermediate portions of the lower arch bar and the upper ends of which are secured to the upper arch bar, thereby providing a very strong and eflicient brace and a bolster opening adapted to receive the springs and the end of the bolster.

I also provide bolster guides which are secured to the inner'faces of the last mentioned U-shaped member. I prefer to make all of these members of approximately U Specification of Letters Patent.

Application filed April 4., 1917. Serial No. 159,824..

or channel shape cross section comprising a flat plate portion connecting the two sides or webs which webs project substantially at right angles therefrom and a flange projecting outwardly at the edge of each web portion. The bars from which these members are constructed may be rolled in a rolling mill or they may be pressed into form by a press, hammer or other suitable means. In order to make a strong and rigid connection, which will also occupy a comparatively small space, Iprefer to nest the ends of the upper member within the ends of the lower member in such a way that the outside portions of the webs of the upper member are contiguous to the inside surfaces of the webs of the lower member and with their flange portions contiguous. These are then secured together by means of rivets passing through the adjacent web and flange portions. Similarly I prefer to nest the channel shape lower portion of the U-shaped central member within the intermediate portion of the lower arch bar member so that their webs are contiguous and the flanges of the lower part of the central member rest upon and are secured to the flanges of the lower member. The upper portions of the central member are contiguous and secured to the webs of the upper arch bar member by means of rivets passing through the adjacent portions and in order to make a stronger construction, I flatten out the flange portions and the bottom connecting plate portions of the central member at the ends thereof, thereby providing amplespace and section for securing its ends to the upper member by means of rivets passing through the same.

I I also provide the usual spring-seats, spring plank, pedestal tie-bars, bolster guides and bolts for connecting and securing the end portions of my side frame to the journal boxes. I also provide a brake hanger support which is secured to the side frame.

Having thus given a general description of my invention, I will now, in order to make the matter more clear, refer to the annexed sheet of drawings which forms a part of this specification and in which like characters denote like parts Figure 1 is a side elevation of a railway car truck, provided with a side frame embodyin my invention; Fig. 2 is a top plan view of the side frame; Fig. 3 is a vertical transverse sectional elevation taken on the line IIIIII of Fig. 2; Fig. 4: is a sectional elevation taken on the line IV-IV of Fig. 3; and Fig. 5 is a section taken on the line VV of Fig. 2.

Referring now to the characters of reference on the drawings :-1 is the upper arch bar shown as of channel section with outstanding flanges 5 at its upper portion and slightly cambered, as shown. The end por tions of the upper arch bar are nested within the corresponding end portions 4: of the lower arch bar 2 and the end portions of the upper flanges of same rest upon the end portions of the flanges 6 of the lower arch bar, as illustrated, and the flanges and webs are secured together by rivet-s, as shown. The lower arch bar is provided with upwardly inclined portions 3, the journal boxes are 7 and the truck column or central memher is 8, this truck column being also of channel section with a bottom plate, two side webs and outwardly projecting flanges at the edges of the webs. This member, as shown, is of U-shape in general form, the lower portion is nested and fits within the lower portion of the lower arch bar 2 and is secured thereto by rivets, as shown, while the upper portion is provided with flattened portions 9, composed of the web portion, the terminal flange portion and part of the connecting plate portions which have been flattened in such a way as to fit closely to the web portions of the upper member and are secured thereto by means of rivets, as shown. The outwardly projecting flange of the truck column or central member is indicated as 10, while 11 and 12 are holes provided in the ends of the arch bars to receive the journal box bolts 13 and 14 for securing them to the side frame. Near the lower external corner of the central member or truck column 8, I provide openings 15 which are adapted to allow a rivet to be passed there-through for securing the end of the pedestal tie-bar 23 to the lower member, as illustrated. In order that the upper end of the truck column may be flattened to fit against the sides of the web of the upper member, I split or divide the flat plate portion for a short distance from its end, as illustrated at 16. The sprin plank which is shown as of channel form, is 17, which is secured to the side frame, as shown, and extends from one side frame to the companion frame on the other side of the car, in order to hold these together and maintain them square and in line. Ihe bolster guides are indicated generally as 19,

provided with flanges 18 by which they are secured to the flanges 10 of the column guide by means of rivets, as shown, those rivets being preferably countersunk on the inner side so as to provide a smooth surface that will not interfere with the movement of the bolster. The bolster springs are 20, the bolster 21 and the brake hanger carriers are 22.

Although I have shown the upper arch bar member of channel form with outstandof channel form with the webs projecting downwardly instead of upwardly, or I may make it of hollow-box, I-beam or other sec--- tion as desired. 7

Although I have described and illustrated my invention in considerable detail, I do not wish to be limited to the exact and specific details thereof as shown and described, but may use such modifications in, substitutions for, or equivalents thereof, as are embraced within the scope of my invention, or as pointed out in the claims.
